Astrophysics teacher | Verified Expert
With a passion for unraveling the mysteries of the cosmos, I specialize in astrophysics. My journey led me through the rigorous halls of the University of North Texas Health Science Center, where I honed my expertise. From celestial mechanics to cosmology, I thrive on guiding students through the wonders of the universe. With a commitment to fostering curiosity and understanding, I'm here to illuminate the stars for learners of all ages and backgrounds. Let's embark on a cosmic exploration together.
